Abstract
Wave functions for mesons and baryons are computed from lattice QCD. They are used to obtain the electromagnetic properties of the low-lying mesons, including charge radii and electromagnetic form factors. Experimental data for the pion and proton electromagnetic form factor fall close to the theoretical lattice computation. Predictions are made for other states. The lepton width of the ϱ, θ and J/ψ are obtained. The wave functions are also used to obtain estimates for isospin splittings and proton decay.
